@micalevisk May I request a review? I've updated the minimal reproduction comments and reproduction procedure above, and I've posted sample code as you suggested - it's a minimal scenario test, so there's a lot of source code.

I've no ideia 🤔

Please provide a minimum reproduction repository. You can start one by running npm init nest in your terminal

@micalevisk I think this issue is related to the import/export behavior of Typescript. What do you think? I think it's right, it suddenly started working again 😑. All import/export code is working fine during the overhaul. I've had a hard time with this, you've had a hard time, so you can rest now.😌

This is the second time this has happened to me.

in src/module/auth/feature/sign-in-user.api.ts

before

: The Request was placed inside the auth module outside the Api class.
import { AuthToken, SignInUserRequest } from '@src-module/auth/feature'

after

: Located in the same folder as the API class
import { SignInUserRequest } from './sign-in-user.request'

I thought it was fixed. It was my mistake. It's hard...

I'll commit the rest of the code to the repository to reflect this, so take a look when you need to.

Let's reopen it first.
because it's impossible to reproduce what happened😑. I don't know how it was fixed.
I don't think it's just an import/export issue with Typescript. I feel like I'm getting lost in a maze...

I'm sure it's just an import/export issue, possibly caused by barrel files (index.ts) introducing a cyclic import in your code, leading to TS metadata being undefined in a specific context
